Ove Descriptio a d Specificatio s
Cooking in a convection oven differs from cooking
in a conventional deck or range oven since heated
air is constantly recirculated over the product by
a fan in an enclosed chamber. The moving air conĆ
tinually strips away the layer of cool air surroundĆ
ing the product, quickly allowing the heat to peneĆ
trate. The result is a high quality product, cooked
at a lower temperature in a shorter amount of time.
Blodgett convection ovens represent the latest adĆ
vancement in energy efficiency, reliability, and
ease of operation. Heat normally lost, is recircuĆ
lated within the cooking chamber before being
vented from the oven: resulting in substantial reĆ
ductions in energy consumption and enhanced
oven performance.

Delivery a d Locatio
DELIVERY AND INSPECTION
All Blodgett ovens are shipped in containers to
prevent damage. Upon delivery of your new oven:
DInspect the shipping container for external damĆ
age. Any evidence of damage should be noted
on the delivery receipt which must be signed by
the driver.
DUncrate the oven and check for internal damĆ
age. Carriers will accept claims for concealed
damage if notified within fifteen days of delivery
and the shipping container is retained for inĆ
spection.
The Blodgett Ove Compa y ca ot assume
respo sibility for loss or damage suffered i
tra sit. The carrier assumed full respo sibility
for delivery i good order whe the shipme t
was accepted. We are, however, prepared to
assist you if fili g a claim is ecessary.
OVEN LOCATION
The well planned and proper placement of your
oven will result in long term operator convenience
and satisfactory performance.
The following clearances must be maintained beĆ
tween the oven and any combustible or nonĆcomĆ
bustible construction.
DOven body right side - 2" (51 cm)
DOven body left side - 2" (51 cm)
DOven body back - 0" (0 cm)
The following clearances must be available for serĆ
vicing.
DOven body sides - 12" (30 cm)
DOven body back - 12" (30 cm)
NOTE: On gas models, routine servicing can usuĆ
ally be accomplished within the limited
movement provided by the gas hose reĆ
straint. I the oven needs to be moved urĆ
ther rom the wall, the gas must irst be
turned o and disconnected rom the oven
be ore removing the restraint. Reconnect
the restraint a ter the oven has been reĆ
turned to its normal position.
It is essential that an adequate air supply to the
oven be maintained to provide a sufficient flow of
combustion and ventilation air.
DPlace the oven in an area that is free of drafts.
DKeep the oven area free and clear of all combusĆ
tibles such as paper, cardboard, and flammable
liquids and solvents.
DDo not place the oven on a curb base or seal to
a wall. This will restrict the flow of air and prevent
proper ventilation. Tripping of the blower moĆ
tor's thermal overload device is caused by an
excessive ambient temperature on the right
side of the oven. This condition must be corĆ
rected to prevent permanent damage to the
oven.
DThe location must provide adequate clearance
for the air opening into the combustion chamĆ
ber.
Before making any utility connections to this oven,
check the rating plate to be sure the oven specifiĆ
cations are compatible with the gas and electrical
services supplied for the oven.
1. Remove the combustion compartment cover.
The rating plate is attached to the frame on the
left side of the combustion compartment.

CANOPY TYPE EXHAUST HOOD
A mechanically driven, canopy type exhaust hood
is the preferred method of ventilation.
The hood should be sized to completely cover the
equipment plus an overhang of at least 6" (15 cm)
on all sides not adjacent to a wall. The distance
from the floor to the lower edge of the hood should
not exceed 7' (2.1m).
The total makeup and exhaust air requirements for

DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exĆ

by a direct flue arrangement.
WARNING!!
It is esse tial that the direct flue be
i stalled as follows. I correct i stallatio

The flue must be class B or better with a diameter
of 6" (15 cm). The height of the flue should rise 6Ć8
ft (2Ć2.5 m) above the roof of the building or any
proximate structure. Never direct vent the oven
into a hood. The flue should be capped with a UL
Listed type vent cap to isolate the unit from exterĆ
nal environmental conditions.
The direct vent cannot replace air consumed and
vented by the oven. Provisions must be made to
supply the room with sufficient makeĆup air. Total
makeĆup air requirements for each oven section
should be approximately 30 CFM (.85m3) per secĆ
tion. To increase the supply air entering the room,
a ventilation expert should be consulted.

Gas Co ectio
GAS PIPING
A properly sized gas supply system is essential for
maximum oven performance. Piping should be
sized to provide a supply of gas sufficient to meet
the maximum demand of all appliances on the line
without loss of pressure at the equipment.
Example:
NOTE: BTU values in the ollowing example are
or natural gas.
You purchase a ZephaireĆG convection oven to
add to your existing cook line.
1. Add the BTU rating of your current appliances.
Pitco Fryer 120,000 BTU
6 Burner Range 60,000 BTU
Deck Oven 50,000 BTU
Total 230,000 BTU
2. Add the BTU rating of the new oven to the toĆ
tal.
Previous Total 230,000 BTU
ZephaireĆ240G 50,000 BTU
New Total 280,000 BTU
3. Measure the distance from the gas meter to
the cook line. This is the pipe length. Let's say
the pipe length is 40' (12.2 m) and the pipe
size is 1" (2.54 cm).
4. Use the appropriate table to determine the toĆ
tal capacity of your current gas piping.
The total capacity for this example is 320,000
BTU. ince the total required gas pressure,
280,000 BTU is less than 320,000 BTU, the
current gas piping will not have to be inĆ
creased.
NOTE: The BTU capacities given in the tables are
or straight pipe lengths only. Any elbows
or other ittings will decrease pipe capaciĆ
ties. Contact your local gas supplier i you
have any questions.

Prior to connecting the oven, gas lines should be
thoroughly purged of all metal filings, shavings,

oven should be checked for correct gas pressure.
The oven and its individual shutoff valve must be
disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.45kPa).
The oven must be isolated from the gas supply
piping system by closing its individual manual
shutoff valve during any pressure testing of the
gas piping system at test pressures equal or less
than 1/2 psig (3.45kPa).

GAS HOSE RESTRAINT
If the oven is mounted on casters, a commercial
flexible connector with a minimum of 3/4" (1.9 cm)
inside diameter must be used along with a quick
connect device.
The restraint, supplied with the oven, must be
used to limit the movement of the unit so that no
strain is placed upon the flexible connector. With
the restraint fully stretched the connector should
be easy to install and quick connect.
The restraint (ie: heavy gauge cable) should be
1,000 lb. (453 kg) test load and should be attached
without damaging the building. DO NOT use the
gas piping or electrical conduit for the attachment
of the permanent end of the restraint! Use anchor
bolts in concrete or cement block. On wooden
walls, drive hi test wood lag screws into the studs
of the wall.
1. Mount the supplied bracket to the leg bolt just
below the gas inlet. ee Figure 10.
2. Attach the clip on restraining cable to the
mounting bracket.
